Became A Part Of Sports Lore In: 1976What It’s Worth: $650,000

In 1974, Aaron broke Babe Ruth's career home run record by blasting his 715th beyond the wall. But the ball from that run isn't his most coveted. The most precious piece of "Hammerin' Hank" memorabilia is the ball from his final home run on July 20, 1976, his 755th blast, which set the record until Barry Bonds surpassed it. A groundskeeper at Milwaukee's County Stadium retrieved the ball in the empty left-field stands and was fired by the Brewers for not turning it over. A fair trade, considering what it ended up being worth.
